A pair of clamping devices are positioned around the pipe and frictionally engage its outer surface. Nut and bolt assemblies connect the front plate with the clamps. These assemblies pull the front plate tight against the pipe end face. A back plate is positioned transversely within the bore of the pipe. The plate has a stem that slidably projects forwardly through a central aperture in the front plate. The back plate carries an O-ring. A nut is threaded onto the stem and functions to draw the back plate forward so that the O-ring seals the interface of the front plate and pipe end face."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for closing and sealing the open end of a pipe","description":"The tool comprises a front plate for closing the open end of a pipe.
